Time dependent analysis of progressively erected structures

Abstract: A specialized software " TDA has been developed for the time-dependent analysis of structures which combine different structural systems, materials and methods of construction. During construction these structures utilize different static systems, new structural members are gradually assembled or cast, post-tensioning is applied and temporary elements are removed. The account is taken of the creep and shrinkage of concrete. The linear aging viscoelastic theory is applied. The mean properties of a cross-section, and the average relative humidity and member size are taken into account. The finite element method is used for structural analysis. The examples of analyzed structures are given in the paper.
